If you have some code that REQUIRES double precision note that
eSignal's language is based on JavaScript. JS's native calculations
are all done in double precision. I've written many eSig routines -
simple and complicated - and have never experienced any problems with
their arithmetic calculations.
In AB I have written a routine that computes a best fit curve to the
price data. The calculation uses the Gaussian Elimination method.
Solving the matrix ends up taking the difference between two large
numbers - AB used to blow up every 50 or so bars. I traced the
problem to the time values on the x-axis. I was able to copy just the
prices to a calculation array and match it with my date array that
used small numbers. This solved the problem.

program. This may have been true in the past but with cheap multi-gig
drives, it is a ridiculous excuse.
